DESCRIPTION:Our planet naturally produces a variety of radio emissions\, g
 enerated by lightning activity and geomagnetic storms driven by the Sun. T
 hese natural radio waves are at the lower end of the radio spectrum in the
  audio-frequency range\, so-called because they have the same frequencies 
 as audible sound waves. We use a Very Low Frequency Receiver\, located at 
 Halley Research Station in Antarctica\, to record these emissions. Halley 
 is a great location to detect these waves because it is magnetically conne
 cted to the outer radiation belt where some of the signals are generated a
 nd is electromagnetically “quiet”\, being far from man-made sources. A
 t the British Antarctic Survey\, we use this radio wave data primarily to 
 investigate the science of space weather storms\, to help us understand th
 e impact of space weather on the Earth-Climate system\, and for lightning 
 detection. As a remarkable spin-off\, conversion to sound reveals a series
  of weird and wonderful noises\, known as the ‘sounds of space’. In th
 is presentation\, we will explore the amazing variety of natural ‘sounds
 ’ detected at Halley\, Antarctica and then embark on a sound-led\, data-
 driven journey from Earth-orbit to beyond the galaxy! I will then describe
  how these remarkable ‘sounds’ have been used in art-science collabora
 tions to create performances\, new music\, and short films. Finally\, I wi
 ll show how the recordings from Halley have been used to enhance the explo
 ration gameplay in the space simulation video game Elite Dangerous.\n\nFor
  further information visit our ‘sounds of space’ web page (https://www
 .bas.ac.uk/project/sounds-of-space/) or read my cover article\, entitled 
 ‘turning the sounds of space into art’ (https://academic.oup.com/astro
 geo/article/60/2/2.18/5380747) in the April 2019 issue of Astronomy and Ge
 ophysics.\n\nDr Nigel Meredith is a space weather research scientist at Br
 itish Antarctic Survey. He uses satellite data to develop global models of
  plasma waves in near Earth space for input into radiation belt codes and\
 , ultimately\, to forecast space weather. He is also interested in extreme
  space weather and has recently applied extreme value analysis to long-ter
 m satellite datasets to determine the 1 in 10\, 1 in 50 and 1 in 100 year 
 space weather events. This is important for assessing the impact of extrem
 e events on the world’s satellite fleet. He enjoys exploring how to make
  scientific data more accessible and is currently involved in an art-scien
 ce collaboration\, ‘sounds of space’. He has published 111 papers in p
 eer-reviewed journals covering a wide range of topics in space plasma phys
 ics.\n\nThe talk will be at the usual location of the Wolfson lecture thea
 tre in the Department of Chemistry\, shown on the map here: https://map.ca
 m.ac.uk/#52.197868\,0.125487\,19\,52.197816\,0.125093\n\nTickets are £2 o
 r free for members. Annual membership (£7) and life membership (£12) can
  also be purchased at the event – cash or card. The talk will be followe
 d by refreshments outside the lecture theatre.\n\nThis talk is part of the
  Cambridge University Astronomical Society (CUAS) series.\n
